SRAM RED AXS DUB 12V Mono crankset

The heart of the drivetrain, the 12V SRAM Red AXS Dub Mono crankset 46 crankset is designed for demanding cyclists in search of the best-performing equipment. 

Like the double-decker version, it features hollow carbon cranks for greater lightness and an oversized aluminum axle for improved rigidity. It uses a 4-point star geometry, allowing quick and easy chainring changes with a single tool.

Combined with an X-range cassette starting with a 10-tooth sprocket, the crankset guarantees a wide development range, while offering the aerodynamics and simplicity of a mono drivetrain. However, the most frequently used sprockets feature progressive gearing (only 1 tooth). 

This versatility makes it equally at home on road bikes, cyclo-cross bikes, gravel bikes and touring bikes. And should you wish to install a double chainring drivetrain at a later date, the Mono crankset can be converted using the same cranks.

The Red AXS is used with the Sram Dub bottom bracket. This standard has the advantage of fitting almost any frame thanks to its universal system, so you don't have to change cranksets at the same time as your bike.
